To help ensure that you specify the correct MTIS kit for an application, Meritor is pleased to provide the following guidelines concerning the length of the thru-tee tube, which depends on the type of axles and wheel-ends on the trailer. For Installation on Meritor TN/TQ Axles with Tapered Spindles Specify kits having thru-tee assemblies with 3.5” long tubes when the trailer axles are equipped with ductile iron hubs. If the trailer axles are equipped with aluminum hubs, specify an MTIS kit containing thru-tees with 4” long tubes. For Installation on Meritor TP Axles with Parallel Spindles Specify kits having thru-tee assemblies with 4” long tubes when the trailer axles are equipped with ductile iron hubs. If the trailer axles are equipped with aluminum hubs, specify an MTIS kit containing thru-tees with 5” long tubes. MTIS Kit Part Numbers “Partial” MTIS Kits “Partial” kits do not include spindle press plugs or stators. Partial kits are for installation on axles prepped for MTIS. (The spindle press plugs and stators have been installed on the axles.) Note that the standard thru-tee length for partial MTIS kits is 3.5”. If you require a longer thru-tee length, please inform your Meritor customer service representative when placing your MTIS order. When a length other than the standard 3.5” is specifi ed, it will be stated in the kit part number. Refer to the following table for examples. (Thru-tee Tube Length) Recommended MTIS with Thru-TeeTube Standard MTIS Kit ThermALERT™ Kit Trailer Axle and Hub types Length Number Example Number Example TN axle with ductile iron hubs 3.5” 32712-22 H2712-22 TN axle with aluminum hubs 4” 32712-22-4 H2712-22-4 TP axle with ductile iron hubs 4” 32712-22-4 H2712-22-4 TP axle with aluminum hubs 5” 32712-22-5 H2712-22-5 “Full” MTIS Kits “Full” MTIS kits are for installation on axles not previously prepped for MTIS. These kits include spindle press plugs and stators. The standard thru-tee tube length for a full MTIS kit is based on the spindle type for which the kit is intended. For example, a full MTIS kit for a TN axle will have a standard thru-tee tube length of 3.5,” while a full MTIS kit for a TP axle will have a standard thru-tee tube length of 4”. If you require a thru-tee length longer than the standard length, please inform your Meritor customer service representative when placing your MTIS order. When a length other than the standard is specifi ed, it will be stated in the kit part number. Refer to the table below for examples.

Most commercial vehicles are large in size with more than two axles. Maneuvering them around tight corners, narrow roads, and spaces is a difficult job if only the front axle is steerable. Furthermore, wear and tear in tires will increase as turn angle and number of axles are increased. This problem can be solved using rear axle steering technology that is being used in commercial vehicles nowadays. Rear axle steering system technology uses a cylinder mounted on one of rear axles called a steering cylinder. Cylinder control is the primary objective of the real axle steering system. There are two types of such steering mechanisms. One uses master and slave cylinder concept while the other concept is relatively new. It goes by the name of smart axle, self-steered axle, or smart steering axle driven independently from the front wheel steering. All these different types of steering mechanisms are discussed in this study with detailed description, advantages, disadvantages, and safety considerations.

  • Analysis and Optimization of the Double-Axle Steering Mechanism with Dynamic Loads
    26 The Open Mechanical Engineering Journal, 2012, 6, (Suppl 1-M2) 26-39 Open Access Analysis and Optimization of the Double-Axle Steering Mechanism with Dynamic Loads Gang Qin, Ying Sun, Yunqing Zhang* and Liping Chen Center for Computer-Aided Design, School of Mechanical Science & Engineering, Huazhong University of Science and Technology, Wuhan, Hubei 430074, P.R. China Abstract: A hierarchical optimization procedure for the optimal synthesis of a double-axle steering mechanism used in truck with dynamic loads is presented. A multibody model of double-axle steering mechanism is presented to characterize the leaf spring effect. The influences of dynamic loads, the motion interference of steering linkage resulted from the elastic deformation of leaf spring, and the effects of wheel slip angles and the position discrepancies of wheel speed rotation centers are studied systematically. A hierarchical optimization method based on target cascading methodology is proposed to classify the design variables of double-axle steering mechanism into four levels. A double-axle steering mechanism for a heavy-duty truck is utilized to demonstrate the validity of the proposed method. The simulation results indicate that the hierarchical optimization procedure is effective and robust. And as a result, it will surely be widely used in engineering.

    LEAF SPRING REPLACEMENT ON AN EXISTING AXLE BEAM TI-345 AXLES AND SUSPENSION Purpose This document outlines the process for replacing the double-eye leaf spring components on an existing axle beam assembly. The following procedure is applicable for both underslung—when the leaf spring is mounted, or "slung", under the axle—and overslung—when the leaf spring is mounted, or "slung", over the axle (Fig. 1). Fig. 1 Underslung Overslung NOTE: Images used in this document are for reference only when assembling, installing and/or operating this product. Actual appearance of provided and/or purchased parts and assemblies may differ. Safety Read and understand all instructions before installing or operating this product. Adhere to all safety labels. The trailer MUST be supported per manufacturer's recommendations before working underneath. Failure to do so may result in death, serious personal injury, severe product and/or property damage. Always lift the trailer by its frame and never by its axle or suspension. Axle and suspension components are not designed, or rated, for the dead weight, point-of-contact loads that the trailer's frame is. Do not go under the railer unless it is supported by appropriately rated jack stands. Improperly supported trailers can collapse, causing possible serious personal injury or death. Moving parts can pinch, cut or crush. Keep clear and use caution. Wear appropriate personal protective equipment (PPE) when performing service or maintenance operations. Always wear eye protection when servicing trailer axles, brakes, hubs, springs and wheels. Not using PPE may result in personal injury.
